Description
Technical field
The present invention relates to the mould for manufacturing prefabricated basal seat area base, wherein, it is provided for by subtracting material CAM method systems
Make the prefabricated basal seat area base of the basal seat area of artificial tooth.
The invention further relates to using this mould manufacture basal seat area base method and profit in this way with this mould
The basal seat area base of son manufacture.
Therefore, present invention finally relates to the local plastic artificial tooth (partial denture) for dentist field or its basal seat area and
The manufacture of all-plastic artificial tooth (complete denture), it makes by machine according to CAM methods (CAM computer-aided manufacturing).It is false
Tooth and basal seat area are preferably being built in the case of CAD methods (CAD CADs) area of computer aided.Make first herein
Basal seat area is made, patient's jaw bow of its anodontia that then reclines or local anodontia.These artificial tooths are then produced individually and filled
Enter in basal seat area and be fixed there.The basal seat area for laying artificial tooth then constitutes finished product artificial tooth.
Background technology
Practices well is that likeness in form makes artificial tooth.That is, in order to make basal seat area, analogy method is used mostly at present, now,
First to the non-sporing anaerobes modulus of patient.One mould is made by the molding, the mould is made with the yellowish pink plastics note of tooth.Plastics are solid
By secondary operation to obtain intended shape after change.Then, it is being fabricated separately and it is current also mostly be likeness in form make artificial tooth quilt
Load.
In order to make artificial tooth, artificial tooth is made by hand and is individually placed in wax support.The wax artificial tooth in the next step by
Then to be moulded after gypsum with hot water wash paraffin removal support and providing for artificial tooth in the embedded cuvette equipped with gypsum
The cavity of material.These artificial tooths are now stayed in gypsum.Corresponding gypsum is injected into or filled in cavity, and people are solidifying in plastics
Gu artificial tooth or finished product artificial tooth are obtained afterwards.
When setting up the tooth largely produced, adjust and polish tooth to adapt to by Dental Technician and perhaps also by dentist
The respective oral conditions of patient.
Such method is disclosed by the A1 of WO 91/07141, herein, basal seat area be based on stamp by unit of plastic milling into.
